The pain in primary osteoarthritis of the knee. Its causes and treatment by osteotomy.
1. Some results of a clinical investigation of patients with osteoarthritis of the knee are described. 2. The different varieties of pain which occur in osteoarthritis are detailed. 3. A sub-group of patients with primary osteoarthritis of the knee is described. In this group "venous" pain predominated; the venographic appearances are typical, and in a large proportion of cases the veins outside the bone are manifestly abnormal. 4. It is suggested that venous congestion within the bone results from extra-osseus vein disturbances, and leads to congestive bone pain and to progressive joint degeneration. 5. The mechanism by which osteotomy produces relief of pain is analysed and discussed. 6. A simple procedure which reproduces some of the benefits of osteotomy is described.
Dolorous calcification of the lateral sesamoid bursa of the great toe.
A case of painful calcification within a sesamoid bursa of the great toe is presented. This may be the first description of painful calcification of this site.
Cobb repair for tibialis posterior tendon rupture.
The tibialis posterior is the main dynamic stabilizer of the hindfoot against a valgus deformity. Its rupture results in hindfoot valgus with a considerable biomechanical disturbance and functional loss in the affected foot. A new method of reconstruction of this tendon is described which involves the use of half the tendon of tibialis anterior.
